Definition of Acyloins. Meaning of Acyloins. Synonyms of Acyloins

- standard oxaziridine did not result in an acyloin. Reduction of acyloins give diols. Oxidation of acyloins give diones. α-hydroxy ketones give positive...
- Acyloin condensation is a reductive coupling of two carboxylic esters using impure metallic sodium to yield an α-hydroxyketone, also known as an acyloin...
- and R−C(=O)−CH2−CH(OH)−R' (beta). Alpha-hydroxy ketones are also called acyloins. They are commonly formed by condensation or reductive coupling of two...
- Normally such compounds are disfavored components in equilibria with acyloins. One special case is catechol, where the C=C subunit is part of an aromatic...
- aromatic aldehydes or glyoxals (OCH=CHO), and results in formation of an acyloin (−C(O)CH(OH)−). In the classic example, benzaldehyde is converted to benzoin...
- a carboxylic acid. Other routes to vic-diols are the hydrogenation of acyloins and the pinacol coupling reaction. 1,3-Diols are often prepared industrially...
- hydroxyketones and alpha hydroxy imines. Reactions of type 4 are also called acyloin rearrangements. While similar to the pinacol rearrangement, the semipinacol...
- Finn, John (1 August 1984). "Synthesis of α-hydroxycarbonyl compounds (acyloins): direct oxidation of enolates using 2-sulfonyloxaziridines". The Journal...
- cheaper oxidant. Alternatively, vicinal diols or their oxidized sequelae (acyloins or α-hydroxy acids) can be oxidized with cleavage to two aldehydes or an...
- pyrolysis. Pairs of esters are coupled to give α-hydroxyketones in the acyloin condensation As a class, esters serve as protecting groups for carboxylic...
